True story: Back when I lived in Japan, I owned a children's folding chair that sat directly on the floor without any legs. It clicked into place so you could adjust your reclining angle and flattened out for easy storage. It was my favorite piece of furniture ever, and I used it almost exclusively to place videogames. I still have it stored in my closet even though it doesn't work properly anymore.
What am trying to say is that I would love a quirky replacement with "a plenty function that the game is developed because of the enjoyment." This multi-function gaming chair looks like it could fit the bill, arriving in a variety of colors and with a versatile reclining back that doubles as an arm rest. However, I worry what people would think of my choice of furniture. The brown model above already looks like a horse with its head above the water, but at their worst, these chairs could be confused with props intended for erotic escapades. Or maybe that's just me.
Amazon Japan is currently selling these... objects... for 7895 yen (about $101) each. Is cold judgment from your peers worth the high price of luxury? Only you can answer that for yourself.
